This application claims the priority under 35 USC §119 of Provisional Application 60/625,852 entitled “Shower Curtain Bar” filed on Nov. 8, 2004 and having John S. DeWees as an inventor. Application 60/625,852 is herein incorporated by reference in its entirety but is not prior art.
Shower curtains, like shower doors, are used to hold water from a shower within a shower enclosure (e.g., shower stall, tub). Typically a shower rod is used to hold the shower curtains. The shower rod, as the name would suggest, is a cylindrical tube having a circular cross section. The shower rod extends across an opening in the shower enclosure. The shower rod may be permanently affixed to the shower enclosure walls using some type of mount. Alternatively the shower rod could be designed to provide tension so that it may be temporarily affixed to the walls. The tension may be provided by a spring bracket or other means. The shower curtains are hung on the rods typically with hooks. The hooks slide on the rod and the shower curtain moves with the hooks.
A problem with the typical shower rod is that the cylindrical shape may make it apt to rotate either within the mount or on the wall. Due to the construction of the typical rod and the circular cross section there is typically little or no flexibility in the rod. Accordingly, if a door was opened and hit the rod the rod would not give and the round cross section of the typical rod can mar the door. Moreover, the impact of the door opening can effect the integrity of the rod or the mounting of the rod. For example, a spring tension rod may fall if enough tension is lost when the rod either is moved or rotates when hit by a door. Additionally, the mounts used to hold the rod may loosen as they absorb the shock of a door hitting the rod.
The limited flexibility also makes installation of the rod more complicated as the rod can not be flexed to fit into a mount. Another problem with installation of a rod is that due to the circular cross section the edge of the rod needs to be parallel to the wall or receiving portion of the mount. If the walls are not parallel or if the rod or mounts are not installed level the edge may not be parallel and portions of the edge may not be in contact with the wall or mount. For a spring loaded rod this may result is less surface area providing the tension and a less stable connection. In addition, a rod can not easily be installed in shower enclosures not having two parallel walls due to the circular cross section. That is, the mount and the edge of the rod need to be at the same angle so that the mount can receive the rod. For a spring loaded rod, the edge would have to be formed to have a specific angle that aligned with the walls.
Additionally, a rod can not easily be formed to other shapes that may be desirable. For example, it may be desirable to have a shower rod that traced the curvature of a tub. However, due to the circular cross section of the rod the rod would require straight ends surrounding a curved portion so that he rod could be received by a mount. Such a configuration of different portions is not desirable and may not be ascetically pleasing. Additionally, if the rod needed to be shortened or the amount of arc needed to be reduced it would require cuts to each end of the rod so as to maintain the arc in the middle. Moreover, unless the straight portions were of significant length, the length of the curved rod could not be shortened too much without eliminating the straight portions.
Furthermore, using a shower rod doesn't allow a curtain to lay flat. Rather, if the shower curtain is placed directly on the rod the roundness of the rod will show through the curtain. If hooks are used the curtain may be folded or pleated where the hooks are located. Moreover, the round cross section may cause friction with some fastening systems.
Accordingly, there is need for an apparatus to hang shower curtains that is not apt to rotate, is flexible, does not require an edge to be parallel to the wall or mount it is to be installed on, can be formed to different shapes and or sizes, can easily be modified and provides an aesthetically pleasing look (e.g., allows the curtain to lay flat).
A shower curtain bar is provided to hold shower curtains. The shower bar has a rectangular cross section with a flat front face. The rectangular cross section means that the bar is not apt to rotate. The flat front face helps prevent doors from being marred as they make contact with the bar. The shower bar may be made of a flexible but strong material so that the bar can be twisted to aid in installation and support the weight of the shower curtains. For example, the exact formation of the bar can change to support installations that are not exactly in accordance with specifications (e.g., non parallel walls). The flexibility may also absorb contact from a door. Mounting brackets may be used to support the bar. The brackets may be formed as mirror images of one another so only a single fabrication is required. The mounting brackets have a groove formed therein for receiving the bar. The grove may be larger than the bar to provide additional flexibility in installation. The mounting brackets may be mounted to the walls using screws that can be inserted into holes that are formed therethrough. The mounting bracket may include a set screw that can be used to help hold the bar in place.
According to one embodiment, the shower bar may be curved for certain installations. For example, for shower stalls that only have one or two walls the shower bar may be curved so as to form a stall for an individual to shower within. According to one embodiment, the shower bar may be curved (arced) to follow an arc of a tub (e.g., edge between tub portion and platform portion). The curved showed bar enables a shower curtain hanging therefrom to drape within the outer edge of the bathtub thus keeping the water within the tub while at the same time providing use of the entire tub. The curved shower bar has a particular arc and depth to it depending on the specifications of the tub that it is used with. The arc and depth can be modified by cutting a single edge of the bar.
The shower bar can be used with shower curtains that use hooks or with Hookless® shower curtains, such as those described in U.S. Pat. No. 5,186,232. The shower bar enables the shower curtains to lay flat against the bar. The shower bar may include designs on the face of it.
The features and advantages of the various embodiments will become apparent from the following detailed description in which:
FIGS. 1A-B illustrate perspective and cross-sectional views of an example shower bar, according to one embodiment;
FIGS. 5A-B illustrate top views of an example shower bar installation between two parallel walls, according to one embodiment;
FIGS. 5C-D illustrate top views of an example shower bar installation between two perpendicular walls, according to one embodiment;
FIGS. 7A-C illustrate various types of curtains installed on an example shower bar, according to one embodiment; and
The bar 100 has a length 110, a height 120 and a width (depth) 130 associated with it. The length 110 is dictated by size of space that it is to be installed in (e.g., size of opening of shower enclosure). The height 120 and the depth 130 of the bar 100 may be selected so as to provide the necessary support as well as an aesthetically pleasing look. It should be noted that it is possible that the height 120 and depth 130 may vary based on the length 110 of the bar 100. According to one embodiment, a top edge 140 of the bar 100 may be rounded. The rounded edge 140 may provide an aesthetic look as well as to provide a smooth surface for a shower curtain to slide on. As illustrated, the exemplary shower bar 100 has a height 120 of 1 inch and a depth 130 of ⅛th inch. However, the bar 100 is in no way intended to be limited by the illustrated dimensions as variations of these parameters are well within the scope of the current invention.
The bar 100 may be made of a light weight material. The bar 100 may be made of a relatively strong material that can support the weight of shower curtains as well as possibly a shower liner. The bar 100 may be made of a flexible material to allow the bar to be flexed during installation to make installation easier. The bar 100 may also flex when a door bangs into the bar 100 so as to not damage the door or the bar 100. That is, the flexibility in the bar enables the bar to flex in so not to damage the bar 100 or the object hitting the bar and to not put undue stress on the components holding the bar 100 (e.g., act as a safety bumper). The bar 100 may be made of a material that can be cut (e.g., with a hack saw) if the length of the bar 100 needs to be shortened.
The bar 100 may be formed by molding (e.g., extrusion, injection, poured). The material may be an aluminum material such as a variation of the 6000 series of aluminum. According to one embodiment, the bar 100 may be made of solid 6021 aircraft aluminum that provides a flexible but yet strong bar 100. The material may be plastic (e.g., PVC, acrylic, ABS). Alternatively, the bar 100 may be stamped or may be machined. The bar 100 may have an anodized finish applied to provide enhanced exterior rigidity.
The receiving face 220 and the mounting face 230 may be parallel to one another. The upper and lower faces 260, 270 may be parallel to one another. The front face 240 may be perpendicular to the receiving face 220 and the mounting face 230. The mounting face 230 may be longer that the receiving face 220. The interior face 250 may be angled to connect an inner edge of the receiving face 220 to an inner edge of the mounting face 230. The holes 280 may be formed on the angled interior face 250 so that as to be closer to the wall. However, the shape and configuration of the mounting bracket is in no way intended to be limited to that illustrated. For example, the receiving face 220 and the interior face 250 may be a single face so that the mounting bracket 200 was pyramid shaped (a triangular cross section). Additionally, the mounting bracket 200 need not be screwed to the wall but could be connected in numerous manners that are either permanent, semi-permanent (removable) or temporary. For example, the mounting bracket 200 could be connected to the wall with nails, tape, glue, or Velcro.
The receiving face 310 has a groove 360 formed therein for receiving a shower bar. The slanted face 340 has a hole 370 formed therein that extends through the mounting bracket 300 and exits the mounting face 320. The hole 370 may receive a screw 380 to secure the mounting bracket 300 to a wall. The hole 370 includes a wide portion 372 and a narrow portion 374, and has a ledge 376 formed between the two. The screw threads can pass all the way through the hole 370 into the wall while the head of the screw may pass through the wide portion 372 but can not pass throw the narrow portion 374 so it comes to rest on the ledge 376. This embodiment allows the screw to be counter sunk (or recessed) within the slanted face 340. According to one embodiment, filler caps (not illustrated) may be provided that fit within the holes 370 to cover the screw head.
According to one embodiment, a set screw (not illustrated) is included that can be used to hold the bar within the groove 350. The set screw could be placed on an upper or lower surface (not illustrated) of the mounting bracket 300. Alternatively, the set screw may be placed in the front face 330 or the inner face 340.
According to one embodiment, the bar may be adjusted within the groove 360. The grove 360 may have a width and height that is wider and longer then the width and height of the bar to accommodate any necessary adjustments and/or so that the bar need not be inserted at an exact angle. For example, if the walls to which the mounting bracket 300 connect are not level the groove 360 may not be perfectly straight. If the shower walls to which the mounting brackets 300 are to be connected are not parallel the grooves 360 in each mounting bracket 300 may not be at the same angle. If the mounting brackets 300 were not installed at the same height and/or depth the bar would enter each groove 360 at a different angle.
The mounting bracket 300 may be made of a light weight but sturdy material. For example, the mounting brackets 300 may be made of white metal such as zinc powder. Alternatively, the mounting brackets 300 may be made of plastic. The mounting bracket 300 may be cast molded. Alternatively, the mounting bracket may be machined or injected. The mounting bracket 300 may be plated and/or lacquered. The mounting bracket 300 may be designed so the same bracket can be used to support either end of the shower bar (e.g., the left and right brackets are identical). The mounting brackets 300 may be solid with the only open area in the bracket being the groove and the holes or may be partially hollow.
FIGS. 5A-B illustrate several different example shower bar/mounting brackets embodiments connected to two parallel (or near parallel) sidewalls.
FIGS. 5C-D illustrate several different example shower bar/mounting brackets embodiments connected to two perpendicular (or near perpendicular) walls 522. In these embodiments, a shower curtain hanging from the shower bar 500 may act as the third wall of a shower stall.
The embodiments of FIGS. 5A-D included a straight bar 500. A straight bar may not always be desired. In some embodiments a curved bar may be desired. For example, a bathtub that is used as a shower may have a curved shape to the opening of the tub (e.g., tub is wider at center then at ends). A straight shower bar aligned with the narrower ends of the tub may result in lost shower area as the shower curtain will be draped in the shower as opposed to along the wall of the tub at the center point. Conversely, aligning a straight shower bar with the center of the tub may result in the shower curtain draping outside the tub at the ends, thus allowing water to run down the shower curtains outside the tub. Accordingly, a shower bar that was curved to follow (or reasonably follow) the curvature of the tub would be desired. Utilizing a curved shower bar may enable the shower curtain to drape substantially along the edge of the tub, which may enable an individual to utilize the entire tub while at the same time maintaining water within the tub. Moreover, a curved shower bar may provide additional room when it is used as a third wall between two perpendicular walls. A curved shower bar may also be used when only a single wall is available with which to mount the shower bar. Furthermore, a curved shower bar may look aesthetically pleasing regardless of what configuration it is used (between two parallel walls, between two perpendicular walls, or connected to a single wall).
The shower opening 630 and the curvature of the tub will dictate the arc (angle) 640, the maximum distance 660, and accordingly the overall length of the shower bar. According to one embodiment, the curved shower bar 600 can be made to fit certain standard sized tubs. As illustrated, the exemplary shower bar 600 is designed to fit a tub that has an opening 630 of approximately 60 inches (from wall to wall) and has an edge that extends out a maximum distance 660 of approximately 8 and ½ inches. Accordingly, the angle 640 may be approximately 30 degrees and the overall length may be approximately 63 inches. However, the invention should in no way be construed to be limited to the embodiment illustrated. As previously mentioned, variations of these parameters are well within the scope of the current invention. As one of ordinary skill in the art would recognize, specifications of the bar (e.g., amount of curvature (arc), length) are dependent on size and shape of the tub.
The bar 600 may be made of the same materials and in the same fashion as the bar 100 of
The flat surface of the shower bar enables the bar to accommodate all types of shower curtains. Moreover, any type of fastening systems (e.g., hooks) can be used with the shower bar. In fact, the flat bar and curved upper end provides less friction that a standard shower bar so that shower curtains and/or fasteners slide easier on the shower bar. Moreover, using the shower bar enables the shower curtains to lay flat. When the shower curtain lays flat it gives the shower curtain a much cleaner and nicer look (e.g., the look of a drapes).
FIGS. 7A-C illustrate various types of shower curtains being connected to an exemplary shower bar 700.
According to one embodiment, the bar (e.g., 100, 600) may be fabricated as a single piece and be packaged and sold that way. According to another embodiment, the bar may be fabricated in pieces so that it can be packaged in a more compact manner. The pieces may be connected together in any manner that would be known to one of ordinary skill in the art. For example, connecting pieces of the bar may have male and female pieces that can be connected or snapped together. The connecting pieces may include hooks that connect together. According to another embodiment, the bar may be one piece that is hinged in several locations and can thus be folded or bent so as to allow for more compact packaging.
According to one embodiment, the bar may come in decorative colors or have decorative designs formed thereon.
According to one embodiment, the mounting brackets may extend along the mounting wall to provide additional surface area for contact. The additional contact provides additional support to hold the bar in place as well as to help avoid the bar and/or brackets rotating.
As previously mentioned, the mounting bracket connects to shower walls. The shower walls may be drywall, tile, and/or a tub insert. The mounting brackets may be bolted to the wall by using toggle bolts, molly bolts, anchors or other connection apparatus. Many of the connection apparatus require that a relatively large hold be drilled in the wall so that the connection apparatus (e.g., toggle bolt) can be inserted through the hole and then open within the wall to hold in place. If the shower wall is a tub insert, the large hall probably extends through the insert into the wall behind the insert so that the wall can provide the support as the tub insert is likely a thin material that can't provide the support for the mounting brackets itself. Bolting the mounting brackets to the wall behind the tub insert is likely to create stresses on the insert. According to one embodiment, inserts (e.g., polypropylene) can be used to provide support for the tub insert.
